Indeed! This would be a tremendous addition to the MP-201. It would be extremely cool if it also offered V/Oct and Hz/V output options (the latter for those of us with older non-Moog CV gear).
To be clear, what the Multipedal will do right now is, you can âdrawâ any kind of MIDI-CC messages in your sequencer, send that CC to the Multipedal and get a corresponding voltage output. This means rhythmic modulations, sequenced changes being sent to Moogerfooger controls, and that sort of thing. Itâs super fun and useful.
What you canât do right now, is to send standard MIDI notes to the Multipedal and get a corresponding voltage output. Itâs only set up to respond to continuous controller data, up to four simultaneous CCs (one per channel) corresponding to four channels of analog output.
Some kind of rudimentary midi note to cv/gate implementation might eventually be something we could add to the multipedal, but weâll have to see. There are some potential hardware limitations since MIDI notes to CV wasnât something we originally designed the hardware to do. I will say that we have a laundry list of cool features that we already plan to implement in future firmware updates, so weâll get through those and then see what a Midi notes to CV feature might look like.
Somebody asked about clock dividers; I will be filming a new little demo later today where I send master clock from a hardware sequencer to control both Ableton Live and the Multipedal, and then use the LFOs from the Multipedal to control various things within Ableton Live, and possibly some Moogerfoogers as well, all synced to the master clock at various beat divisions. Iâve had a lot of fun testing this feature and have gotten it working really well.
Anna and I just got our Multipedals (#s 15 & 16 - Yes, 2 of em - So I guess we have some Multi Multipedal action going on now) ⌠Instant gratification using it when PAIRED WITH MY MODEL D!!! YIKESâŚ
I got a chance @ Namm this year to mess with the Mp201 into the Voyager and LP. So I already new how well it paired with those. Youâd expect it to, being that all 3 are in production by Moog currently..
But plugging it in to the Model D was amazing.. Being able to have an extra LFO ( or 4 ) especially being that the MP201âs LFOs are capable of S&H, which the mini D didnât have is GREAT⌠MP201->Model D Filter CV IN=Amazing.. Also using the expression pedal to sweep the whole pitch range of the model D can cause tremendously crazy sounding SHTUFF!!! Like going from the lowest possible note (F in Range '32 - C in Range '2) And all without any steps.. Like butter from low to high and high to low⌠It sounds like the craziest pitch shifter youâve never heard!
I also did some really basic filter sweeping in unison with the Voyager and Model D.. It was really fun the sweep em both at the same time, while still having a hand free to play each keyboard!!..
This is gonna make our live shows WAY more interesting and sonic! We are SOO Stoked..
I will make a Video soon and put it on Youtube of my Model D and Mp201!
In my response to the question about converting MIDI Notes to CV, I kept using the term âMIDI/CV conversionâ when I meant to say âMIDI Note/CV conversionâ. Apologies to all for the confusion this caused.
As Amos confirms in his post, the Multi-Pedal does indeed provide MIDI/CV conversion by translating incoming MIDI CC messages to CVâs (but not incoming MIDI Notes). This capability is explained on page 37 of the Userâs Manual.
MIDI/CV conversion offers many useful possibilities with all types of CV gear. For example, using a DAW or Sequencer program to control Moogerfoogers through the Multi-Pedal (via MIDI CC messages), you could:
Synchronize the MuRFâs tempo or the delay time of the Analog Delay to an external sequence
Create your own custom stepped rhythmic patterns with the Low Pass Filter or Phaser
Generate pitch sequences by controlling the Ring Modulator Carrier Oscillator or FreqBox Oscillator
These are just a few simple examples, and no doubt youâre already thinking of many others. The Multi-Pedalâs MIDI/CV conversion offers hundreds of control possibilities with Moogerfoogers, the Voyager or the Little Phatty (and this is just one facet of what the Multi-Pedal can do!)
Thanks for the clarification on this. I thought I understood you about the MIDI Notes/CV thing initially, but then you referred to it as âMIDI/CVâ and I wasnât sure. Fortunately, Amos was able to respond and give us the complete story.
A question for you or Amos: if the Multi-Pedal can convert MIDI CCs to CVs, and there are 128 CC values (0-127), does that mean that you get stepping at the CV output of the Multi-Pedal as the values change? And is that what the CV Smoothing function is used for?
You asked a couple of very astute questions - you must have read the manual! Iâll take a stab at providing you with an answer. Amos may wish to elaborate or provide additional info here.
First, itâs important to point out that for the Multi-Pedal to convert MIDI CCs to CVs, the Channel Mode should be set to âExpressionâ (if the Channel Mode is set to âGateâ, incoming MIDI CC messages are used to turn the Gate ON or OFF at the analog output, and if the Channel Mode is set to âLFOâ, incoming MIDI CCs will affect the output depending upon other settings - either way, you donât get MIDI/CV conversion). You must also be sure that your transmitted MIDI data matches the Channelâs programmed MIDI settings as described on page 37 of the Userâs Manual.
Now, on to your questions:
Yes, the Multi-Pedal will produce a stepped output as it converts MIDI CC values to Control Voltages. The voltage value of each individual output step depends on the setting of the CV Scale parameter (found in the Utilities menu). Some simple math reveals the step voltage values:
When CV Scale is set to âUnipolarâ (0 - 5V), a step value is equal to 5 volts divided by 128, or 0.039V.
When CV Scale is set to âBipolarâ (-5 to +5V), a step value is equal to 10 volts divided by 128, or 0.078V.
2. No, the CV Smooth function (also found in the Utilities menu) does not smooth converted MIDI CC voltages. The purpose of CV Smooth is to smooth out the LFO waveform when the LFO is set to very high rates (i.e. frequency). Since the LFO signal is generated digitally, high frequency LFO waves can get choppy as they approach the Multi-Pedalâs output sample rate; when it is switched ON, the CV Smooth function acts to even things out a bit, resulting in a smoother effect. Of course, the choppiness of high frequency LFO waves can also produce some interesting effects depending on how you apply them - this is the reason why you have the option of turning CV Smoothing ON or OFF.
Currently, the Multi-Pedal has no function that Iâm aware of for smoothing the stepped output that results from the MIDI CC conversion process (perhaps an option to be added in a future update?). So what can you do when you need a smooth CV output converted from a stream of MIDI CCs? If you have a CP-251 CV Control Processor, you can route one of the Multi-Pedal CV outputs to the Lag Processor and adjust the RISE and FALL controls to eliminate stepping (Iâve tried this and it works great). You could also avoid the issue entirely if you are able to use an LFO synced to MIDI Clock to accomplish the same effect youâre trying to achieve, especially if all you need is a smoothly rising voltage (try a SAW UP wave) or a falling one (try a RAMP DOWN wave).
A couple of other things to note about the Multi-Pedalâs ability to convert MIDI CCs to CVs. One is that the conversion takes place regardless of whether the associated Channel is ON or OFF (weâre talking Expression Mode exclusively here, not Gate or LFO Mode). For example, letâs say youâve got Channel 1 in âExpression Modeâ, switched ON, properly configured and currently working to convert a stream of MIDI CCâs to a CV. Then you switch Channel 1 OFF by pressing FS1. This disables the Expression pedal function, but does not turn off the conversion process - you will continue to get an output on CV1 corresponding to the MIDI CC values being transmitted. Not only that, but the intensity of the Channel 1 Footswitch LED will continue to vary, indicating the approximate output voltage level of the converted MIDI CC values. Pretty cool, eh?
Any thoughts on how I might go about programming a series of MIDI CC values to create a musical scale by controlling the Freqbox oscillator from the Multipedal? Thatâs what Iâm really interested in.
Actually, I have had some luck in converting Atari-style controller jacks to MIDI. Following that logic, and the fact that the paddle controller was a 50K ohm linear pot, I imagine that the mulipedal COULD indeed be rigged to play Super Breakout and other games utilizing the paddle controller without voiding the warranty. Maybe someday Iâll break down, buy a multipedal, and use it with my Coleco Vision Atari emulator module thing.
